INSULATED RAIL-JOINT.

Specification of Letters Patent'.

Patented J an. 21 1908.

Beit knownthat I, PHILIP JOHN D-ALTON, a citizen of the United States, residing at Joliet, in the-county of Will and State of Illinois, `have invented certain new and useful Improvements in Insulated Rail-Joints, of

whlch the following is a speciiication.

-This invention relates to the subject of insulated joints, and has in view the provision of a. practical and effective joint of this character. j

To'this end the invention contemplates an nsulatedrail joint embodying in its construction a rm andsubstantlal metal base support for the rails and a'thorough insulation .of all of the joint parts.

'A furtherobject of the invention is to provide-a strong and effective'base insulationconstituting a part ofthe su porting base which receives the load or weiglht of the trafic on the rails, while :at the same time being s odesigned and arranged as to be firmly supacv tion, but a l`shown in t ported. or braced against tendency to ow underthe' pressure of the loado'n the rails.v

f l Another object of the invention is to provide -a construction wherein the mechanical `and elements of thejoint are interlocked ,and heldI against relative displacement, while there is preserved the feature of separability of all of the joint parts and insulation for convenience and facility in vassem- .blijng and separating the same. l

' With these and many other objects' in i view which Willimorev readily appear to those familiar with the art as the nature of the 1nvention is better understood, the same con'- `sists in the novel construction and arrange ment. of parts hereinafter more fully described, illustrated, and' claimed.

The essential features of the invention lare necessarily susceptible to modification, withf out departing from the scope of the invenplreferred 'embodiment thereof is e accompanying drawings,v in which:

- Figure 1 is a side elevation oflan insulated` railjoint constructed in accordance withthis invention. Fig. 2 is a sectional perspective 'view on the line .2-142 of Fig. 1. Sis a detail crosssect'ionalview on the line 3`3v of Fig. 1. 4 is a detail in perspective cfa section of t e formof base late embodied in the construction shown in igs. 1', 2, and 3..

Fi .-5 is a side elevation of a modiiediformof rai joint embodying the invention.

is a sectional perspective view on the line 6-6 of Fig. 5. Fig. '7 is a detail perspective view of a section of the form. of base plate embodied in the joint shown in Figs. 5 and 6.

Fig. 8 is a sectional perspective view of al1-- The improvements contemplated by this 4, invention are susceptible to embodiment in v different forms of joints, but in all adaptaw tions the same essential features are preis well exempliiied by the form of 'insulated served. However, the construction claimedrail joint shown in Figs. 1, 2, 3,`and 4 of the and referring iirst to this construcdrawings,

be observed that the joint illustion, it will v trated in saidl organization the adjacent service or running rails 1 and 2, the opposite side angle bars 3, the joint bolts 4 havingthe usual. head and nut members 5 and 6, and a main metal base plate 7 having a separable interlocking engagement with both angle bars, as will pres# entl appear. The side angle bars 3 are of 'dup icate design and construction, and each .of the same is provided with a main splice I bar portion 8y having the usual bolt holes for the reception of the joint bolts 4, and with a foot flange 9 overlying the base iiange of the rrails, as plainly shown in Fig. 2 of the draw.

S- .s A distinctive feature of the present invenfrom the longitudinal side edges of the base v vplate 7 and preferably forming an integral part of the latter. j d

The shouldered section of the foot flange ofeach angle bar may b`e proyided inf a,

variety of ways, but in the joint shownin the groupof Figs. 1 to 4' inclusive, the construc- Ition referred to is provided by forming the foot flange of each angle bar with an exiigures includes in its general tended'cut-out keeper notch 1 1. This notch extends for a greater ortion of the length of. y

the .ane bar 'and pro uces'at the. endi'sgahere .of ase holding shoulders Also. thetra bar forms, at the bottoml corners thereof, the terminal securing legs 13 which are disposed in substantially vertical planes, and` project below the planeof the rail bases, said terminal securing legs being provided at their lower ends with outturned spiking vflanges 14.

The bas/e support or base plate 7 is preferably designed to extend the full length of the joint to afford a substantial support for both rail ends, and the saine preferably consists of a solid body portion provided with the said integral side upstanding girder iianges 10 which are designed to project upwardly to any desired length and fit into thekeeper notches 11 of the angle bars. -The end portions of the girder fianges which project upwardly into the keeper notches 1 1 between the oppositely located terminal securing legs 13, are formed with upright retaining shoulders 15 which oppose and coperate with the base holding shoulders 12 of the angle bars, thereby providing what has been termed a separable interlocking engagement between the angle bars and the base late. This serves to securely lock and ho d the same against longitudinal displacement, while lateral displacement of the base plate is entirely obviated by reason of the fact that the side girder flanges 10 thereof project above the plane of the rail bases, and, beyond the hold ing shoulders 12 thereof, the girder `flanges are narrowed, yas indicated at 16,- to form flange extensions lying behind and against the terminal securing legs 13. The said base plate `7 may also be provided, ifdesired, with a corrugated bottom surface as suggested in Fig. 2 of the drawings.

To provide for the insulation of the mechanical elements referred to, the invention contemplates as one of the prominent features thereof the employment of a main insulating base piece 17 This base piece preferably consists lof a filler or filler block of wood., lignum vitae preferred, which is .seated on and confined within the fianged base plate or base support 7, and is intended to extend the full length of the base plate to provide a 'firm and substantial insulating base support for both rail ends. In connection with the base filler piece or block 17 there may be employed, if found desirable or practical, a pair of metallic bearing plates 18 interposed between the fiat top surface of the base piece or block 17 and the rail bases. ln'the use of these bearing plates, as shown in the drawings, one of the same is associated with each rail end so that the latter has its individual bearing plate support on top of the insulating base piece or block 17. In'.

order to properly and firmly secure the individual bearing plates 1S in position, the same are preferably provided withv the flanged ends 19 constituting terminalV holding ianges deflected downwardly and seated in recesses long cut-out keeper notch 11 of each angle f provided therefor in the base piece or blockI 17. 'l`he inner flanged ends 1.9 of the scparate bearing'plates are spaced apart, and

receive in the interval therebetween the base using side insulating sheets .22 interposed between the rail sides and the rail adjoining faces of the angle bars. These insulating sheets 22 follow the conformation ofthe rail sides and angle bars and are provided with bottom apron extensions 23 which project downwardly in Vertical planes below the rail bases and lie at the outer side edges of the base plate 17 and the bearing plates 18 between such edges and the ygirder flanges il) of the base plate, thus securing avery coinpact and effective base insulation for the joint. The joint bolts'l are insulated by nleans ofl any of the well known bolt insulations, pref erably by means of insulating sleeves or hushr ings 24 arranged within the bolt holes of the angle bars, and the insulating washers at the inner sides of the head and nut members of the bolts. In connection with the insulating washers 25 there are' associated the usual metal backing washersZ.

In the form of the invention shoun vin separable interlocking engagement between the angle bars and the upstanding girder flanges of the base plate. This mmilication suggests the expedient of forming the pendent edge portion 27 lof the foot 'flange t) of cach angle bar with a plurality of alternated reversely disposed holding shoulders 2S which interlock with the complementari matching correspondingly arranged retaining shoulders 29 formed on and along the upper edge' of the side girder flanges l()a `of the base plate 7 a. '.lh'is modified formof 'base plate 7 l is illustrated as having a plainbody portion instead of the corrugated bottom surface of the plate 7 previously referred to, and in addition to having the seriesofA reversely disposed and alternated shoulders 29, said modified lforni of base plate 7a is formed at opposite side edges thereof, and intermediate its ends, with the 'pendent stiffening flanges .'30 which serve to stiifen and reinforce the 'base plate in the, vertical plano 'of the oint between the meeting ends of the rails. In other respects the modified struc-r ture shown -in Figs. 5, (i, and. 7 is..substantially the saine as thelconstruction o i jointv already described and similar reference ico` leo

- plate 7 b. trated as terminating within the plane ofthe ably constructed withvthe side spiking flanges characters will apply to similar parts in the j "two forms of joints.

In theform of joint `shown in Figs. 1 and 2 of the drawings thekeeper notch 11 in the angle bars extends wellinto the inclined porltion of t-hefoot flangeoverlying the rail flanges, but a modification-of this construction is'suggested in Figs. 8 and 9 of the draw' ings wherein the foot flanges 9 of the angle bars are illustrated as being fprovided at their f outer edges with pendent ange extensions 31 in which are formed long-keeper notches 11a within which register plain, comparatively low, girder flanges 10b arising from opposite portions of the body of the base These girder flanges 10b are illuskeeper notches l1a of the angle bars, and the body portion of the base plate is continued out to the ends of the joint, to afford a full length support for the insulatingbase piece or block. In addition to the girder flanges 10F the modified form of plate 7b is prefer- 32 arranged outside ofthe vertical plane of the flanges 10b and provided between the ends of the plate body with pendent stifenin vflanges or girders 33.

arious other modifications will suggest themselves to those skilled in the art, and it will therefore be understood that changes in the form, proportion, and minor details of construction .may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
